Title:
MEASUREMENT SYSTEM
Document Type and Number:
Japanese Patent JP2019219206
Kind Code:
A
Abstract:
To provide a measurement system with which it is possible to measure a measurement point without installing a retroreflector at the measurement point.SOLUTION: There is provided a measurement system 1 including a flight device 2 which is remote controllable, a position measuring device 3 capable of performing distance measurement, angle measurement and tracking, a remote control device 4 for controlling the flight of a flight vehicle and capable of communicating by wireless with the flight device 2 and the position measuring device 3. The flight device 2 is provided with a shaft 5 tiltably supported in a discretionary direction, a retroreflector provided at the lower end of the shaft 5, and a flight vehicle camera 9 provided coaxially with the retroreflector. The position measuring device 3 tracks the retroreflector, and the remote control device 4 is provided with a display unit for displaying a flight vehicle camera image and the measurement result of the position measuring device 3 and a terminal arithmetic processing unit, the terminal arithmetic processing unit causing the flight vehicle to flight until a desired measurement point is detected in the flight vehicle camera image and computing the three-dimensional coordinate of the measurement point on the basis of the measurement result of the retroreflector and the positional relationship between the optical axis of flight vehicle camera in the flight vehicle camera image and the measurement point.SELECTED DRAWING: Figure 1
